A large percentage of the world population are actually vitamin addicts and don't know it. Put it in another way: They are actually nutrient dependents in that they require much larger amounts of nutrients such as amino acids, Ascorbic Acid, N Acetyl Cysteine and dozens of other body-native substances because their bodies require much larger amounts to run and operate efficiently. Without adequate nutrient levels your body falls out of equillibrium or homeostasis and will eventually develop metabolic problems that will manifest as "dis-eases" and even drug and substance addictions! You may think taking a daily multivitamin or whatever concoction you discovered on your own without testing works, but how do you know for sure, and why do you still feel and act the way you do?
Vaping is probably the best ways to get around your frequent body and mind-destroying habits we call smoking. This too is a wide area but in the context of cigarette addiction, we need to realize the largest addictive component to smoking is not nicotine or tar, but the oral fixation and action of putting objects to your mouth. Vaping has been shown to be the most effective harm reduction strategy to conquer your addiction to cigarettes and the frequent supplementary addiction of alcohol consumption.
Causes of cigarette craving relatively unknown
Did you know that most smokers of tobacco and other combustibles are actually hypoglycemic? Their blood sugar spikes up and down like a yo-yo. People are actually allergic to the very substances they crave and don't know it, and their doctor's don't tell them this because they don't know about it either! Yet again, the so-called "first line treatment" for any kind of addiction of substances is usually more drugs that alter your body and mind - some more than others in varying degrees. The end result is more biochemical modification, degradation of cells and cellular structure, and further problems down the cellular stream.
